Trigonometric Functions

Overview

The trigonometric functions are functions of an angle. They relate the angles of a triangle to the length of its sides. Normal trigonometric functions include sine, cosine, and tangent. There are also inverse trigonometric functions such as arcsine (sin^-1), arccosine(cos^-1) and arctangent (tan^-1).

Hyperbolic Functions

Hyperbolic functions are analogs of the ordinary trigonometric functions. The basic hyperbolic functions are sinh, cosh, and tanh. There are also inverse hyperbolic functions such as arcsinh (sinh^-1), arccosh(cosh^-1) and arctanh (tanh^-1).
